At the request of the RSGB VHF manager to support the WRC19 push for 4MHz at 50MHz, G8GTZ and G8LES conducted some RBTV tests today and achieved what we believe is probably the first 2 way DATV QSO on 6mts - edit, well it wasn't see below!

Using transverters / upconverters we had the first 2 way QSO over 7.5Kms from IO91KD to IO91LC - MER was in excess of 20dB and G8LES transmitted H265 pictures over DVB-S2 16APSK giving some high quality images at 1.1 mbit/sec.
